/*******************************************************************************
* Function Name : TIM_ClearITPendingBit
* Description : Clears the TIMx's interrupt pending bits.
* Input : - TIMx: where x can be 1 to 8 to select the TIM peripheral.
* - TIM_IT: specifies the pending bit to clear.
* This parameter can be any combination of the following values:
* - TIM_IT_Update: TIM1 update Interrupt source
* - TIM_IT_CC1: TIM Capture Compare 1 Interrupt source
* - TIM_IT_CC2: TIM Capture Compare 2 Interrupt source
* - TIM_IT_CC3: TIM Capture Compare 3 Interrupt source
* - TIM_IT_CC4: TIM Capture Compare 4 Interrupt source
* - TIM_IT_COM: TIM Commutation Interrupt
* source
* - TIM_IT_Trigger: TIM Trigger Interrupt source
* - TIM_IT_Break: TIM Break Interrupt source
* Output : None
* Return : None
